摘要
在当前的数控加工技术中,三轴数控加工技术已得到普遍应用且已相对的成熟。但随着五轴加工技术的发展与推动,五轴加工技术所拥有的高效率,短周期,高质量,低成本等优越性逐渐凸现出来,是一种重要的加工技术。在工件加工过程中,工件3D模型的建立是数控加工中至关重要的环节。对类似于马鞍这种具有复杂型面的工件,通过MATLAB软件对鞍形曲面数学模型进行编程运算,生成数学模型的关键点。将关键点以dat的格式导入UG中,并利用UG中通过点生成面的命令完成鞍形曲面精确的三维实体模型的建立。在工件模型的基础上,进行数控加工工艺路线的规划及仿真,实现了MATLAB、UG相结合的数控加工方法,大大缩短了复杂型面数控加工的生产周期。
Three axis numerical control processing technology has been widely used and relatively mature in the current NC machining technology. With the development and promotion of the five axis machining technology,the advantages of high efficiency,short period,high quality and low cost of the five axis machining technology has been gradually emerged. It is an important processing technology. In the process of machining,the establishment of the 3 D model of the workpiece is one of the most important parts in NC machining process. A work piece with complex curved surfaces,such as a saddle,generating the key points of mathematical model by programming operation of MATLAB software. Import the key points in the dat format into UG software,and complete the accurate 3 D solid model of the saddle surface by point generating surface commands. Based on the model of the work piece,the machining technology process of the saddle is analyzed and processing simulation is practiced,which realized the numerical control machining method combining MATLAB and UG. It greatly shortens the production cycle of complex surface NC machining.
